What attorneys should know about retrospective appraisals

Q: What is a retrospective appraisal?

A retrospective appraisal is a valuation prepared as of a past effective date — date of death for estate work, date of filing or separation for divorce, date of contribution for charitable donations. The inspection happens today; the value opinion is anchored to the historical date. USPAP Standards 1 and 2 govern the work product the same way they govern a current-market appraisal — the only difference is which comparables are admissible and how the data after the effective date is treated.

Q: Is a retrospective appraisal admissible in court?

Yes. A USPAP-compliant retrospective appraisal signed by a state-certified appraiser is the standard evidentiary form for valuation as of a past date — accepted by Utah district courts in divorce and probate matters, and accepted by the IRS for estate tax (Form 706) and gift tax (Form 709) filings.

Q: Can you do a retrospective valuation for any past date?

Practically, yes — as long as adequate comparable-sale data existed in the market at the effective date and reasonable evidence of the subject property's condition at that time can be reconstructed. The further back the effective date, the more work it takes to verify market conditions; for dates more than 5–7 years prior, expect a slightly longer turnaround and ask about MLS access.

Why date-of-death and divorce-date valuations follow different rules from current-market work — and exactly how to brief your appraiser to avoid revisions.

A retrospective appraisal asks one straightforward-sounding question: what was this property worth on a specific date in the past? In practice, it's one of the most procedurally fragile assignments an appraiser handles, and the report's defensibility is largely determined before the inspection — by how the engaging attorney briefs the work.

What follows is a working Utah residential appraiser's view of how to engage retrospective work without the round-trips, missing disclosures, and IRS-friction that costs everyone billable hours.

What is a retrospective appraisal?

A retrospective appraisal estimates a property's market value as of a specific historical "effective date" — typically a death, a divorce filing, a casualty loss, or a charitable transfer. The valuation must rely only on data that was available on or before that effective date. Hindsight is contamination.

In Utah, the most common triggers attorneys see:

Date-of-death valuations for estate tax (IRS Form 706) and step-up in basis under IRC §1014.
Charitable contribution appraisals under IRS Pub 561 for non-cash donations of real property over $5,000.
Casualty loss baselines establishing pre-event value before fire, flood, or eminent domain proceedings.
Divorce filings in Utah's equitable-distribution framework, where the marital-asset valuation date is often the date of separation rather than the trial date.
Gift tax (Form 709) where a transfer's value at the moment of conveyance must be defended.

Why retrospective ≠ current

If you've never engaged this work before, the easiest mistake is assuming a retrospective appraisal is just a current-market appraisal with a different date label. It isn't.

A current-market appraisal pulls comparable sales from the most recent 90–180 days, applies adjustments, and reconciles to a value as of "today." A retrospective appraisal pulls comparables that closed on or before the effective date, ignores everything that happened after, and adjusts as if today's appraiser were standing in the property's shoes on that date.

The Wasatch Front market alone has moved through three distinct phases since 2020 — pre-pandemic equilibrium, 2021–2022 escalation, and post-2023 plateau — so a date-of-death effective in March 2022 versus March 2024 produces wholly different defensible numbers from the same property in Salt Lake County, Utah County, or Summit County.

Time-adjusted comparables, condition assumptions documented as of the effective date, and a clean market-conditions analysis are the load-bearing pieces.

What attorneys should provide upfront

Most revisions trace back to a brief that lacked one of these pieces:

The effective date — explicitly. "Date of death, March 14, 2024" is unambiguous. "Last spring" is not.
The intended use. Estate tax filing, gift tax, divorce settlement, charitable substantiation, and casualty loss each carry different reporting expectations under USPAP Standards Rule 2-2. The intended use determines what disclosures the report must contain.
The intended users. The IRS, a specific trust, a court, and an estate's attorneys are all distinct named users — the report is restricted to them. A retrospective valuation prepared for a trustee cannot later be handed to the IRS without a use-expansion or revision.
Property condition as of the effective date. Photos taken within weeks of the date are gold. Failing that: a written description from the executor, a prior listing photoset, or insurance carrier records. Improvements made after the effective date must be backed out; deterioration that occurred after must be ignored.
Any prior valuation work. If a CPA already estimated value for a tax filing, share it. The appraiser doesn't have to agree with it, but they shouldn't be surprised by it later.

Briefing checklist One brief that includes effective date, intended use, intended users, condition documentation, and any prior valuations saves roughly three round-trip emails — and lets the appraiser scope the assignment correctly the first time.

Common mistakes that trigger revisions

In rough order of frequency:

Requesting "just a current value" when an estate filing actually requires a date-of-death number. The IRS will reject a current valuation submitted for date-of-death basis.
Using current MLS comps without time-adjustment. Even competent appraisers occasionally fail to time-adjust against the FHFA's Utah House Price Index or a defensible local market index. The IRS catches this on review.
Undocumented condition assumptions. "Assumed average condition" is a red flag; specific photos, prior MLS listings, or executor declarations are not.
Mixing intended uses. A divorce-filing appraisal cannot moonlight as an estate filing two years later — the reports must be separately prepared (or expressly expanded), or the analysis is exposed to challenge.
Skipping the alternate valuation date. IRC §2032 lets executors elect a six-months-after-death valuation. Engaging only a date-of-death appraisal forecloses that option without analysis.

USPAP and the Treasury rules — the short version

A retrospective appraisal still complies with USPAP Standards 1 and 2 — same scope of work, same reporting requirements — with an effective-date treatment that explicitly excludes data after the date. For estate tax work, Treasury Reg. § 20.2031-1(b) defines "fair market value" as "the price at which the property would change hands between a willing buyer and a willing seller" and is the legal standard the report must satisfy.

For non-cash charitable contributions over $5,000, IRS Pub 561 requires a "qualified appraisal" by a "qualified appraiser" — meaning USPAP-compliant, signed by an appraiser with verifiable credentials and no disqualifying relationship to the donor. State-licensed Utah Certified Residential Appraisers qualify; signature plus license number on the cover page is the documentation the IRS expects.

Closing

Good retrospective work is half briefing, half analysis. The appraiser determines the analysis quality; the engaging attorney determines half of the briefing quality. When both are tight, you get a report that reads cleanly, defends easily under examination, and doesn't generate revision rounds when the IRS, opposing counsel, or a probate judge starts reading.

If you have a Utah estate, divorce, or contribution-substantiation matter that needs retrospective work, request a quote — most retrospective assignments across Salt Lake, Utah, Davis, Summit, Wasatch, and Tooele counties finish in 5–7 business days from inspection access.

Frequently asked

A valuation prepared as of a past effective date — date of death for estate work, date of filing or separation for divorce, date of contribution for charitable donations. The inspection happens today; the value opinion is anchored to the historical date. USPAP Standards 1 and 2 govern the work product the same way they govern a current‑market appraisal — the only difference is which comparables are admissible and how the data after the effective date is treated.

Yes. A USPAP‑compliant retrospective appraisal signed by a state‑certified appraiser is the standard evidentiary form for valuation as of a past date — accepted by Utah district courts in divorce and probate matters, and accepted by the IRS for estate tax (Form 706) and gift tax (Form 709) filings.

Practically, yes — as long as adequate comparable‑sale data existed in the market at the effective date and reasonable evidence of the subject property's condition at that time can be reconstructed. The further back the effective date, the more work it takes to verify market conditions; for dates more than 5–7 years prior, expect a slightly longer turnaround and ask about MLS access.

The property address, the effective date, the intended use (estate Form 706, divorce equitable distribution, charitable contribution Form 8283, etc.), the intended user(s) (executor, IRS, court, both spouses), and any condition documentation from the effective date — photos, repair records, inspection reports. The clearer the briefing, the cleaner the report.

The effective date is when the value opinion applies. The inspection date is when the appraiser physically observed the property. Both are stated on the report cover page. For retrospective work the two are explicitly different, and the report documents condition adjustments between the two dates if needed.

Yes. Most retrospective appraisals never require testimony, but when they do we're prepared. We've been deposed and have testified in Utah district court for estate and divorce matters. Testimony is billed hourly above the report fee; rates available on request.
